I have had this Samsung laptop for the past three years and recently it has been overheating due to the fan either just giving out after a while or just not starting. I shoot compressed air through the vents and no dust comes out so it must be underneath the hood. Would taking my laptop apart and giving the fan a clean be the easiest solution, especially before I purchase a new fan? I can't afford a new computer at the moment so a quick and cheap fix would be great.
